The Use of Diets to Improve the Quality of Life of Women With Breast Cancer.

INTRODUCTION: There has been an increase in the incidence of breast cancer cases in the last decade, and despite the treatment increasing the chances of survival, it reduces the quality of life. In this context, diets could decrease the adverse effects of treatment and improve quality of life. METHODOLOGY: A form with the European Organization for the Research and Treatment of Cancer Quality of Life Questionnaire, which contains specific scores for physical, cognitive, emotional, symptomatic, and functional performance, was made available in a Facebook support group. Afterward, the data were analyzed using linear regression and a t-test of independent samples using Jamovi version 2.3.24 (retrieved from https://www.jamovi.org). RESULTS: There was a low number of participants who followed the ketogenic diet or intermittent fasting. In general, adherence to the diets was good. In the t-test, diets showed improvement in physical performance. Linear regression correlated treatment with chemotherapy, metastases, and bad diet adherence with worse symptomatic scores. CONCLUSION: There is evidence that diets can improve the symptoms of these patients; however, there is no consensus about which diet produces the best effect, requiring further studies on this subject.

The interplay between climate change and ageing: A systematic review of health indicators.

Climate change and rapid population ageing pose challenges for communities and public policies. This systematic review aims to gather data from studies that present health indicators establishing the connection between climate change and the physical and mental health of the older population (≥ 65 years), who experience a heightened vulnerability to the impacts of climate change when compared to other age cohorts. This review was conducted according to the PICO strategy and following Cochrane and PRISMA guidelines. Three databases (PubMed, Scopus and Greenfile) were searched for articles from 2015 to 2022. After applying inclusion and exclusion criteria,nineteen studies were included. The findings indicated that various climate change phenomena are associated with an elevated risk of mortality and morbidity outcomes in older adults. These included cardiovascular, respiratory, renal, and mental diseases, along with physical injuries. Notably, the impact of climate change was influenced by gender, socioeconomic status, education level, and age-vulnerability factors. Climate change directly affected the health of older adults through ambient temperature variability, extreme and abnormal temperatures, strong winds, sea temperature variability, extreme El Niño-southern Oscillation (ENSO) conditions and droughts, and indirectly by air pollution resulting from wildfires. This review presents further evidence confirming that climate change significantly impacts the health and well-being of older adults. It highlights the urgency for implementing effective strategies to facilitate adaptation and mitigation, enhancing the overall quality of life for all individuals.

Estudo retrospectivo de estimativa de idade óssea através da maturação cervical por meio de tomografia computadorizada de feixe cônico (TCFC) / Retrospective study of bone age estimation through cervical maturation using cone-beam computed tomography (CBCT)

Estimar idade óssea em pacientes é de suma importância para estabelecer um protocolo de tratamento adequado e ainda subsidiar outras análises e mesmo decisões de natureza administrativa, policial ou forense. A tomografia computadorizada por feixe cônico TCFC, dentre várias aplicações, pode ser um meio de obtenção de dados para estimativa de idade óssea em pacientes jovens. O objetivo do estudo foi, além de avaliar a acurácia do método de Baccetti et al. (2005) para obtenção do índice de maturação cervical (IMC) das vértebras cervicais C2, C3 e C4, obter por meio de medidas de área vertebral e intervertebral C2-C4 em plano sagital de tomografia computadorizada por feixe cônico (TCFC), uma fórmula de regressão que possa ser utilizada amplamente para a estimativa da idade entre 10 e 18 anos completos. Foram analisadas tomografias de 73 pacientes no intervalo etário de interesse, obtidas medidas de área em corpo de vértebra e espaços intervertebrais e estabelecidos índices IMC para cada um. Regressão linear simples foi realizada e duas fórmulas foram obtidas com poder explicativo de 59% da distribuição (R2) considerado o erro padrão de 1,3 anos (NC 95%). Em pós-teste considerada a margem de erro de 1,5 anos verificou-se um índice de acerto de 74% na predição da idade cronológica. Os dados de IMC obtidos neste estudo não foram satisfatórios e não demonstraram boa correlação com a progressão etária entre 10 e 18 anos de idade. Observados os propósitos e os limites deste trabalho, concluímos que a TCFC pode e deve ser utilizada para estimativa de idade óssea em indivíduos em crescimento.

ENDOCANNABINOID SYSTEM IN THE PARAVENTRICULAR NUCLEUS OF THE HYPOTHALAMUS MODULATES AUTONOMIC AND CARDIOVASCULAR CHANGES BUT NOT VASOPRESSIN RESPONSE IN A RAT HEMORRHAGIC SHOCK MODEL.

ABSTRACT: We evaluated the participation of the endocannabinoid system in the paraventricular nucleus of the hypothalamus (PVN) on the cardiovascular, autonomic, and plasma vasopressin (AVP) responses evoked by hemorrhagic shock in rats. For this, the PVN was bilaterally treated with either vehicle, the selective cannabinoid receptor type 1 antagonist AM251, the selective fatty acid amide hydrolase amide enzyme inhibitor URB597, the selective monoacylglycerol-lipase enzyme inhibitor JZL184, or the selective transient receptor potential vanilloid type 1 antagonist capsazepine. We evaluated changes on arterial pressure, heart rate, tail skin temperature (ST), and plasma AVP responses induced by bleeding, which started 10 min after PVN treatment. We observed that bilateral microinjection of AM251 into the PVN reduced the hypotension during the hemorrhage and prevented the return of blood pressure to baseline values in the posthemorrhagic period. Inhibition of local 2-arachidonoylglycerol metabolism by PVN treatment with JZL184 induced similar effects in relation to those observed in AM251-treated animals. Inhibition of local anandamide metabolism via PVN treatment with URB597 decreased the depressor effect and ST drop induced by the hemorrhagic stimulus. Bilateral microinjection of capsazepine mitigated the fall in blood pressure and ST. None of the PVN treatments altered the increased plasma concentration of AVP and tachycardia induced by hemorrhage. Taken together, present results suggest that endocannabinoid neurotransmission within the PVN plays a prominent role in cardiovascular and autonomic, but not neuroendocrine, responses evoked by hemorrhage.

Ascophyllum nodosum Extract and Glycine Betaine Preharvest Application in Grapevine: Enhancement of Berry Quality, Phytochemical Content and Antioxidant Properties.

The Douro Demarcated Region (DDR) has peculiar edaphoclimatic characteristics that provide a suitable terroir for premium wine production. As climate change effects continue to emerge, ensuring productivity and quality becomes increasingly important for viticulturists, as those directly determine their profits. Cultural approaches, such as the use of biostimulants, are actively being developed to mitigate abiotic stress. The main objective of this work was to assess the effect of foliar sprays of a seaweed (Ascophyllum nodosum)-based extract (ANE) and glycine betaine (GB) on grape berry quality, bioactive compounds, and antioxidant activity. A trial was installed in a commercial vineyard (cv. 'Touriga Franca') in the Douro Superior (Upper Douro) sub-region of the Douro Demarcated Region. In 2020 and 2021, three foliar sprayings were performed during the growing season, namely at pea size, bunch closure, and veraison. There was a positive effect of both biostimulants (ANE and GB) on the physiological and biochemical performance of cv. 'Touriga Franca' exposed to summer stress. In general, the GB 0.2% spraying was the most promising treatment for this grape cultivar, as it increased berry quality, the concentration of bioactive compounds (total phenolics, flavonoids, and ortho-diphenols), and the antioxidant activity. These results revealed the efficacy of biostimulant sprayings as a sustainable viticultural practice, improving berry quality under summer stress conditions.

COVID-19 in the nervous system: physiopathology and neurological manifestations / Covid-19 no sistema nervoso: fisiopatologia e manifestações neurológicas

Abstract Background Coronavirus disease 2019 (COVID-19) is a viral infection caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Although respiratory manifestations have received greater visibility during the pandemic caused by this virus, numerous neurological complaints related to coronavirus 2 infection have been documented in several countries. These records suggest that this pathogen presents neurotropism, and it can cause different neurological conditions of varying intensity. Objective To investigate the ability of coronavirus 2 to invade the central nervous system (CNS) and its neurological clinical outcomes. Methods The present study consists in a comprehensive literature review of the records available in the PubMed, SciELO, and Google Scholar databases. The descriptors COVID-19, brain and physiopathology, associated with the Boolean operator AND, were used in the search. Regarding the inclusion and exclusion criteria, we selected the papers published since 2020 with the highest number of citations. Results We selected 41 articles, most of them in English. The main clinical manifestation associated with COVID-19 patients was headache, but cases of anosmia, hyposmia, Guillain-Barré syndrome, and encephalopathies were also described with considerable frequency. Conclusion Coronavirus-2 presents neurotropism, and it can reach the CNS by hematogenous dissemination and by direct infection of the nerve endings. It causes brain injuries through several mechanisms, such as cytokine storm, microglial activation, and an increase in thrombotic factors.

Volatile Composition of Fortification Grape Spirit and Port Wine: Where Do We Stand?

Port wine's prominence worldwide is unequivocal and the grape spirit, which comprises roughly one fifth of the total volume of this fortified wine, is also a contributor to the recognized quality of this beverage. Nonetheless, information about the influence of the grape spirit on the final aroma of Port wine, as well as its volatile composition, is extremely limited. Moreover, the aroma characteristics of Port wines are modulated mainly by their volatile profiles. Hence, this review presents a detailed overview of the volatile composition of the fortification spirit and Port wine, along with the methodologies employed for their characterization. Moreover, it gives a general overview of the Douro Demarcated Region (Portugal) and the relevance of fortification spirit to the production of Port wine. As far as we know, this review contains the most extensive database on the volatile composition of grape spirit and Port wine, corresponding to 23 and 208 compounds, respectively. To conclude, the global outlook and future challenges are addressed, with the position of the analytical coverage of the chemical data on volatile components discussed as crucial for the innovation centered on consumer preferences.

Impact of gallic acid on tumor suppression: Modulation of redox homeostasis and purinergic response in in vitro and a preclinical glioblastoma model.

Glioblastoma (GBM) is the deadliest primary brain tumor in adults due to the high rate of relapse with current treatment. Therefore, the search for therapeutic alternatives is urgent. Gallic acid (GA), a potent natural antioxidant, has antitumor and modulatory actions on purinergic signaling. In this study, we investigated the cytotoxic effects of GA on the rat GBM (C6) cell line and on astrocyte culture and analyzed its role in regulating oxidative stress and purinergic enzymes involved in GBM proliferation. Cells were exposed to GA from 50 to 400 µM for 24 and/or 48 h. Next, the effect of GA was evaluated in the preclinical model of GBM. Wistar rats were treated with 50 or 100 mg/kg of GA for 15 days, and cerebral and systemic redox status and degradation of adenine nucleotides and nucleosides in circulating platelets, lymphocytes, and serum were evaluated. Our results demonstrated that GA has selective anti-glioma activity in vitro, without inducing cytotoxicity in astrocyte. Furthermore, GA prevented oxidative stress and changes in the hydrolysis of nucleotides in GBM cells. The anti-glioma effect was also observed in vivo, as GA reduced tumor volume by 90%. Interestingly, GA decreased the oxidative damage induced by a tumor in the brain, serum, and platelets, and, also prevented changes in the degradation of nucleotides and nucleosides in lymphocytes, platelets, and serum. These results indicate, for the first time, the therapeutic potential of GA in a preclinical model of GBM, whose effects may be related to its role in redox and purinergic modulation.

NMDA receptors in the insular cortex modulate cardiovascular and autonomic but not neuroendocrine responses to restraint stress in rats.

The insular cortex (IC) is a brain structure involved in physiological and behavioural responses during stressful events. However, the local neurochemical mechanisms involved in control of stress responses by the IC are poorly understood. Thus, this study aimed to investigate the involvement of glutamatergic neurotransmission within the IC in cardiovascular, autonomic and neuroendocrine responses to an acute session of restraint stress. For this, the selective NMDA glutamate receptor antagonist LY235959 (1 nmol/100 nL) or the selective non-NMDA glutamate receptor antagonist NBQX (1 nmol/100 nL) were microinjected into the IC 10 min before the onset of the 60 min session of restraint stress. We observed that the antagonism of NMDA receptors within the IC enhanced the restraint-evoked increase in arterial pressure and heart rate, while blockade of non-NMDA receptors did not affect these cardiovascular responses. Spontaneous baroreflex analysis demonstrated that microinjection of LY235959 into the IC decreased baroreflex activity during restraint stress. The decrease in tail skin temperature during restraint stress was shifted to an increase in animals treated with the NMDA receptor antagonist. Nevertheless, the blockade of either NMDA or non-NMDA glutamate receptors within the IC did not affect the increase in circulating corticosterone levels during restraint stress. Overall, our findings provide evidence that IC glutamatergic neurotransmission, acting via local NMDA receptors, plays a prominent role in the control of autonomic and cardiovascular responses to restraint stress, but without affecting neuroendocrine adjustments.

Impact of Deficit Irrigation on Grapevine cv. 'Touriga Nacional' during Three Seasons in Douro Region: An Agronomical and Metabolomics Approach.

The introduction of irrigation in vineyards of the Mediterranean basin is a matter of debate, in particular in those of the Douro Demarcated Region (DDR), due to the limited number of available studies. Here, we aimed to perform a robust analysis in three consecutive vintages (2018, 2019, and 2020) on the impact of deficit irrigation on the yield, berry quality traits, and metabolome of cv. 'Touriga Nacional'. Results showed that in the peaks of extreme drought, irrigation at 30% crop evapotranspiration (ETc) (R30) was able to prevent a decay of up to 0.4 MPa of leaf predawn water potential (ΨPd), but irrigation at 70% ETc (R70) did not translate into additional protection against drought stress. Following three seasons of irrigation, the yield was significantly improved in vines irrigated at R30, whereas irrigation at R70 positively affected the yield only in the 2020 season. Berry quality traits at harvest were not significantly changed by irrigation, except for Total Soluble Solids (TSS) in 2018. A UPLC-MS-based targeted metabolomic analysis identified eight classes of compounds, amino acids, phenolic acids, stilbenoid DP1, stilbenoid DP2, flavonols, flavan-3-ols, di-OH- and tri-OH anthocyanins, and showed that anthocyanins and phenolic acids did not change significantly with irrigation. The present study showed that deficit irrigation partially mitigated the severe summer water deficit conditions in the DDR but did not significantly change key metabolites.

Application of Walkability Index for Older Adults' Health in the Brazilian Context: The Case of Vitória-ES, Brazil.

This study follows up on the article 'Walkability Index for Elderly Health: A Proposal', published in 2020, as well its validation in the Historic Center of Porto, published in 2021. The 2020 article presented the theoretical and methodological bases relating qualities of public spaces, the walkability of older adults, and the direct benefits on health. The 2021 article validated the applicability of the index in the Historic Center of Porto, Portugal. Both articles incorporated the factor 'slope', solving a criticism evidenced in related literature about the slope being ignored in older adults' walking conditions studies. The present study, however, aims to validate the conceptual design of the Walkability Index for Elderly Health (WIEH) in the Brazilian context at the historic center of Vitória. The methodology included the analysis and evaluation of public spaces regarding the pedestrian network-urban fabric, urban scene, and safety-and the presence of slopes and/or stairways. Subsequently, these spaces were classified according to the WIEH, ascertaining their level of adequacy for older adults' walkability. The results show that paths friendly to older adults are rare and that the problems encountered focus primarily on the low quality of the pedestrian network and not on the existence of slopes and stairways.

Between absence from Alma-Ata and Prevsaúde: primary health care in the twilight of the Brazilian dictatorship. / Entre a ausência em Alma-Ata e o Prevsaúde:a atenção primária à saúde no ocaso da ditadura.

Drawing on personal documents from Ernesto Geisel and press reports, this article discusses the background to the decision by Brazil not to take part in the International Conference on Primary Health Care held in Alma-Ata, USSR, in 1978. It is suggested that the Ministry of Health and the Ministry of Foreign Affairs had different views on the importance of the meeting in Kazakhstan, resulting in their submitting conflicting recommendations to the president of Brazil. It also investigates how the precepts consolidated in the Declaration of Alma-Ata were shared among Brazilian health specialists of different ideological persuasions, even to the point of serving as a blueprint for programs devised under the dictatorship, with implications for the development of later initiatives.

Com base em documentos pessoais de Ernesto Geisel e matérias na imprensa, o artigo discorre sobre os bastidores da decisão de o Brasil não participar da Conferência Internacional sobre Atenção Primária à Saúde, realizada em 1978, em Alma-Ata, URSS. Sugere que os ministérios da Saúde e das Relações Exteriores avaliaram de maneiras distintas a importância da reunião no Cazaquistão, resultando em encaminhamentos conflitantes ao presidente da República. Estabelecida a ausência brasileira, o artigo traz contribuições acerca das formas pelas quais os preceitos consolidados na declaração de Alma-Ata foram compartilhados pelos círculos sanitaristas no país das mais distintas posições ideológicas, tendo inclusive orientado a formulação de programas ainda no regime militar e com implicações importantes sobre iniciativas posteriores.

Active Aging Governance and Challenges at the Local Level.

International and national guidelines have been promoting active aging while creating the necessary means for decision-makers and other relevant actors to work together (governance mechanisms) to implement local and active aging policies. This is especially important in the present COVID-19 pandemic context, posing greater challenges on older people who tend to be self-isolated. How are local actors conceptualizing active aging? What are their priorities related to a healthy life for older people? Which governance mechanisms are used to implement such policies? These are some of the questions addressed in this paper, targeting Portugal, a southern European country. A mixed-methods sequential explanatory design combining a survey conducted at a national level and interviews with key actors in the NUTS III Aveiro Region was employed to identify and understand the underpinning governance mechanisms. Findings confirm the 'passive organization type' in which European politico-territorial studies tend to place Portugal, as there are gaps in the way policies are formulated, implemented and evaluated, as well as a lack of coordination. Results of this study have important impacts on the way local governments and other stakeholders will prepare themselves in the post-pandemic period to design and implement policies addressing active aging.

Chemical Space Exploration of Oxetanes.

This paper focuses on new derivatives bearing an oxetane group to extend accessible chemical space for further identification of kinase inhibitors. The ability to modulate kinase activity represents an important therapeutic strategy for the treatment of human illnesses. Known as a nonclassical isoster of the carbonyl group, due to its high polarity and great ability to function as an acceptor of hydrogen bond, oxetane seems to be an attractive and underexplored structural motif in medicinal chemistry.

Overexpression of TGF-ß1 induces renal fibrosis and accelerates the decline in kidney function in polycystic kidney disease.

Autosomal dominant polycystic kidney disease (ADPKD) is characterized by the presence of numerous fluid-filled cysts, extensive fibrosis, and the progressive decline in kidney function. Transforming growth factor-ß1 (TGF-ß1), an important mediator for renal fibrosis and chronic kidney disease, is overexpressed by cystic cells compared with normal kidney cells; however, its role in PKD pathogenesis remains undefined. To investigate the effect of TGF-ß1 on cyst growth, fibrosis, and disease progression, we overexpressed active TGF-ß1 specifically in collecting ducts (CDs) of phenotypic normal (Pkd1RC/+) and Pkd1RC/RC mice. In normal mice, CD-specific TGF-ß1 overexpression caused tubule dilations by 5 wk of age that were accompanied by increased levels of phosphorylated SMAD3, α-smooth muscle actin, vimentin, and periostin; however, it did not induce overt cyst formation by 20 wk. In Pkd1RC/RC mice, CD overexpression of TGF-ß1 increased cyst epithelial cell proliferation. However, extensive fibrosis limited cyst enlargement and caused contraction of the kidneys, leading to a loss of renal function and a shortened lifespan of the mice. These data demonstrate that TGF-ß1-induced fibrosis constrains cyst growth and kidney enlargement and accelerates the decline of renal function, supporting the hypothesis that a combined therapy that inhibits renal cyst growth and fibrosis will be required to effectively treat ADPKD.
